This study examines whether persons who attended a breast cancer educa
tion summit or received written materials (i) exhibited improved knowl
edge about breast cancer; and (ii) used the information themselves, sh
ared it with others, or implemented community education/screening prog
rams. Participants (92 lay persons, 67 health professionals who attend
ed; 44 who did not attend but received written materials) were primari
ly female, with a mean age of 47. They completed a 10-item knowledge q
uestionnaire on four occasions (pre-conference, immediately post-confe
rence, 9 weeks, 6 months). On the third and fourth occasion, participa
nts also were asked how they had used the information. Paired samples
t tests revealed that lay individuals (p < 0.001) and health professio
nals (p < 0.001) exhibited improved knowledge of breast cancer after a
ttending the conference, used the information in their personal health
care, and shared it with others, and some implemented education and s
creening programs. Of nonattendees, only the health professional group
retained knowledge gain over time. A conference can produce increased
knowledge about breast cancer and stimulate attendees to use informat
ion for themselves and share it with others. For lay persons, conferen
ce attendance is superior (p < 0.01) to written materials alone, in ac
hieving long-term gain in knowledge.
